Hi
I have enviroment where we try to backup ~1.5Tb data from VNXe CIFS shares with Backup Exec 2012 SP3 to DataDomain 620 (BOOST/OST enabled). Problem is that full backup takes ~40hrs complete and incremental backup also takes ~40hrs. I tested with NDMP trial license and full backup takes 18hrs and incremental backup takes 1-2hrs. So there is quite large time difference.
So I suggested customer that they buy NDMP license but customer disagreed to pay more and demands more accurate explanation why they would need to buy NDMP license. So is there any deep level detailed information how backup is done when backing trough CIFS and when backing trough NDMP? Or solution to make CIFS backups go much faster. I understand that when backing trough CIFS, it needs to be read trough BE agent on media server, but why incremental backup is taking so long?
